Claims priority, application Japan March 9, 1955 2 Claims. (Cl. 112-421) This invention relates to a cloth stitcher by the use of which holes or rents in cloths can be mended by sewing machine with or without the aid of patches. A cloth stitcher that was in general use before this invention consists of two circular frames, the outer one larger than the inner one in diameter. A piece of cloth to be stitched or embroidered is placed on the outer frame and stretched tightly by fixing the inner frame in the outer frame. The cloth thus held is stitched or embroidered. In so far as embroidering is concerned, this device answers the purpose. But in the case of stitching the cloth is stretched in all directions and so it is stretched with the rent widened. Consequently, the stitched-up cloth will lose the balance of its original size. Besides, the users must have frames of different diameters ready at hand because the clearance-space between the outer and the inner frames must be changed according to the thickness of cloth. This causes some inconvenience to them.

The object of this invention is to remove the abovementioned drawbacks. That is to say, using the present cloth stitcher, stitching is done back and forth along both sides of the rent and at right angles to the rent without the rent being widened. Consequently, the stitched-up cloth does not lose the balance of its original size and, moreover, there is no need for various frames of difierent clearance-space ready for different thickness of cloth.

Fig. 1 is a perspective view of the frame. Fig. 2 is a vertical section of the frame. Fig. 3 is a perspective view of how the frame is used. According to the invention, the stitcher is made of a frame 1 integrally combined with a skirt 2 having the shape of a bugles bell, i. e., flaring outwardly. at the lower part, each being constructed of a flexible, elastic substance such as India rubber, syn- 2,815,000 Patented Dec. 3, 1957 ice thetic rubber or vinyl resin. The circumference of the skirt is shaped like the teeth 3 of a saw. The frame has a groove 4 inside and a metal ring 5 is set in the groove.

In using the invention, first place a piece of cloth 6 on the stitcher on the sewing machine table. Next, place the frame on the piece of cloth and press the ring lightly. As the frame is depressed, the skirt will spread outwardly and due to the frictional engagement of the saw-toothed edge 3 of the skirt with the cloth, the cloth will be uniformly stretched. When fully depressed, the under surface of the frame and skirt will contact the face of the cloth to maintain its stretched condition.

The part to be stitched, e. g. rent 9, is now placed right under the needle of the sewing machine with the cloth kept stretched in this way and the frame is moved back and forth along the rent so that the thread 10 as shown in Fig. 3 will stitch the rent. Of course, in this case the ring must be pressed to such a degree as the rent does not widen. One important thing to be remembered in the use of this stitcher is that feed-dog must be removed so that it may not work during stitching.

When a part of cloth has worn out thin or has worn out into a hole on account of friction, put a patch on the part and stitch the outside of the patch in the same manner as described above. In the case of embroidery, just place the part to be embroidered on the stitcher and press the ring.

In short, as the skirt is flexible, the thickness of the cloth to be stitched or embroidered by the stitcher does not matter at all, thus answering the purpose of this invention.

What I claim as patent:

1. A cloth holder for machine stitching and embroidering which comprises an annular frame, an outwardly flaring elastic flexible skirt dependent from said frame, and a metal ring permanently mounted in said frame for supporting the same.

2. The holder of claim 1 wherein the lower edge of said skirt is of saw-toothed configuration.
